United States Patent Oflice 3,203,031 Patented Aug. 31, 1965 3,203,031COMBINATION HINGE AND DETENT Ted L. Youngdale and Louis L. Youngdale,both of 818 Crescent Drive, Vista, Calif. Filed May 31, 1963, Ser. No.284,545 2 Claims. (Cl. 16-145) The present invention relates to hingesgenerally and in particular to a combination hinge and detent structureuseful in cabinet work for mounting doors on openings in cabinets andproviding detent means for holding the doors in the closed position.

An object of the present invention is to provide in a hinge and detentstructure, a device which may be manufactured inexpensively, one whichhas features which allow its use on various types of cabinet doors, andone which has long life characteristics.

Another object of the present invention is to provide a hinge and detentfor cabinet doors which is sturdy in construction, one simple instructure, and one highly effective in action. I

These and other objects and advantages of the present invention wil befully apparent from the following description when taken in connectionwith the annexed drawings, in which:

FIGURE 1 is a fragmentary view of a portion of a cabinet door andassociated jamb, the door being shown partially in section and the jambin section, with the hinge structure of the present invention installedthereon,

the door being shown in closed position,

FIGURE 2 is a view similar to FIGURE 1 showing the door in openposition,

FIGURE 3 is an elevational view,

FIGURE 4 is a view similar to FIGURE 1 showing a modified form of theinvention, the door being shown in closed position,

FIGURE 5 is a view of the assembly shown in FIGURE 4 with the door inopen position,

FIGURE 6 is an elevational view of the structure shown in FIGURES 4 and5.

FIGURE 7 is a view similar to FIGURES 2 and 5 of a second modified formof the invention, the door being shown open,

FIGURE 8 is a view of the assembly shown in FIGURE 7, the door beingshown in closed position,

FIGURE 9 is an elevational View of the assembly shown in FIGURES 7 and8,

FIGURE 10 is a view similar to FIGURES 1, 4, and 8, of a still furthermodified form of the invention, the dotted line showing indicating theswinging movement of the door to open position, and

FIGURE 11 is an elevational View of the structure shown in FIGURE 10.

Referring in detail to the drawings in which like numerals indicate likeparts throughout the several views, and with particular reference toFIGURES 1 to 3, inclusive, the device of the present invention isindicated generally by the reference numeral 12 and it is showninstalled upon a jamb 14 and door 16 of the type conventionallyassociated with cabinets.

The hinge structure or device 12 comprises a first plate member 18 and asecond plate member 20 having their one adjacent ends hingedly connectedtogether in the conventional manner as at 22 in FIGURES 1 and 2.

The first plate member 18 is L-shaped and has its short leg 24 overlyingthe exterior face of the jamb 14. The long leg 26 of the member 18extends over the end of the jamb 14 and projects beyond the inner faceof the jamb 14 as shown most clearly in FIGURE 1.

The second plate member 20 is Z-shaped with the first section 28, asecond or intermediate section 30, and a third or free end section 32.

The first section 28 overlies the short leg 24 of the member 18 and thesecond or intermediate section 30 overlies the adjacent portion of thelong leg 26 when the door 16 is in the closed position. The thirdsection 32 projects perpendicularly with respect to the long leg 26 ofthe member 18 when the door is in the closed position as shown in FIGURE1.

A free rotatable roller 34 carried on trunnions 36 projects from thesection 32 of the second member 20.

A keeper, indicated generally by the numeral 38, is in the path ofmovement of the roller 34 when the door 16 executes its swingingmovement toward and away from the jamb 14.

The keeper 38 comprises a member 40 pivotally connected to a bracket 42which projects from the long leg 26 and biased in one direction by aspring.44 which bears against the long leg 26 of the plate member 18 andalso bears against a shoulder 46 provided on one end of the member 40.

Wood screws, as at 50, are employed to secure the first and second platemembers 18 and 20 to the jamb 14 and door 16, respectively,in theconventional manner.

With reference to FIGURES 4 to 6, inclusive, the plate member 20 isidentical as previously described but the plate member 18' carries onits long leg 26' an S-shaped keeper 52 which is in the path of themovement of the roller 34 on the member 20 when the door 16 executes itsmovement toward and away from the jamb 14.

A portion of the keeper 52 adjacent one end, is secured to the long leg26 by means of a bridge element 54 struck out from the long leg 26' andinto which is threaded a set screw 56 bearing against the adjacentportion of the keeper 52 and locking the same in its position ofadjusted movement relative to the roller 34.

With reference to FIGURES 7 to 9, inclusive, a further modified form ofthe invention is shown in which the plate member 20 has welded thereto ayoke 58 supporting the rotatable roller 60. The long leg 26" of themember 18" supports another keeper 62 by means of a slot element 64struck out from the long leg 26". A set screw 66 threaded through theelement 64 serves to secure the keeper 62 in any position of itsadjusted movement in the path of movement of the roller 60 uponexecution of swinging movement of the door 16 relative to the jamb 14.

With reference to FIGURES 10 and 11 a fourth and final form of theinvention is illustrated in which a first plate member 68, secured tothe jamb 14, has mounted on it a roller 70, a yoke 72 supporting theroller 70.

Another plate member 74, having one end hingedly connected to the platemember 68, is secured to the door 16' and has a portion bent outwardlyfrom the door, as at 76 and provided on its free end with a curvedrecess forming portion 78.

The plate member 74 is also provided with a slot 80 (FIGURE 11), throughwhich projects a hooked end portion 82 of a resilient bar element 84.The other end of the bar element 84 is formed to a recess 86 and betweenthe recess 86 and the portion 78 of the plate member 74 is a spring 88which biases the bar element 84 to the position in which it engages theroller 70.

The bar element 84 also carries an L-shaped stop member 90 which has oneleg bearing against the inner face of the door 16' when the door isclosed as in full lines in FIGURE 10.

When the door 16' has been moved to the dotted line open position,FIGURE 10, the stop element 90 is free from the inner face of the door16'.

When the door is in the closed position the roller 70 bears against theadjacent portion of the bar element 84, as shown in full lines in FIGURE10 and keeps the door 16 in the closed position. Upon opening movementof the door 16' the bar element 84 rolls under the roller 70 from thefull line position to the dotted line position with the spring 88 urgingthe bar element 84 to the position in engagement with the roller 70.

In each of the forms of the invention described there is a keeper on oneof the plate members and a roller carried by the other plate member, theroller and keeper being engageable and acting as a detent to keepthedoor in closed position after it has been swung to closed posit-ion.

While only preferred embodiments of the invention have been shown anddescribed, other embodiments are contemplated and numerous changes andmodifications may be made in the invention without departing from thespirit thereof as set forth in the appended claims.

What is claimed is:

1. In a hinge and detent structure for a door and an adjacent jamb in acabinet, a first plate member adapted for attachment to said door, asecond plate member adapted for attachment to said jamb, hinge meansco-nnect-ing adjacent ends of said first and second members together forswinging movement relative to each other, a freely rotatable rollermounted on one of said members, and a resilient keeper mounted on theother of said members in the path of relative movement of said rollerwith respect to said keeper upon execution of swinging movement of onemember relative to the other, said roller engaging said keeper when saidfirst and second members are at the limit of their swinging movement inone direction relative to each other, a curved recess forming portionappended on the resilient keeper, a resilient bar element extending froma slot'on the other of said members, said bar element extending fromsaid slot and having a formed recess at its end, a leaf springinterposed between :said curved recess forming portion and said formedrecess for biasing the bar element to a position for engaging saidrotatable roller.
